Resource Management

• Fixed BE resource helpers (GetPodBEMilliCPU*, GetPodBEMemoryByte*) to correctly account for init containers and pod.Spec.Overhead per Kubernetes semantics — #2918 (milestone v1.8.1)
• Registered MidCPU / MidMemory into ExtendedResourceNames — #2940

koordlet & Prediction

• Added --default-qos-class-for-guaranteed-pods flag with parse-time validation — #2926
• Introduced computePodSampleWeight for priority-aware and cold-start-ramped histogram weighting in predict_server — #2980

Webhook & Device Plugin

• Refactored pod mutating handler into shared runMutatingPlugins for UPDATE support — #2958
• Replaced binary StatusRejected with structured error codes in webhook metrics — #2944
• Added runtime GPU/NPU resource registration to gpudeviceresource plugin — #2953

C++ · Numerical Methods · Hull-White Model · Compiler Optimization

• Diagnosed and fixed a test failure in testCachedHullWhite triggered specifically under g++ 12.x with -O3 optimization — a subtle floating-point precision issue that only surfaced at high compiler optimization levels — #2435
• Adjusted numerical tolerance in test-suite/shortratemodels.cpp from 1.2e-5 → 1.3e-5 to correctly accommodate valid floating-point variance introduced by aggressive compiler optimizations, without relaxing test integrity

C++ · Memory Management · File I/O · Huffman Coding

A high-performance lossless file compressor leveraging Huffman coding and multi-core concurrency.

• Implemented lossless Huffman compression with mutexes and condition variables for thread synchronization
• Benchmarked on a 500 MB dataset — achieved a 63% reduction in execution latency (25.1s → 9.3s) by scaling from single-threaded to 4-worker concurrent execution

React.js · Vite · Tailwind CSS · Recharts · Codeforces API · Vercel

A responsive single-page analytics dashboard to visualize and compare Codeforces user profiles side-by-side.

• Built a full-featured SPA with React + Vite + Tailwind CSS rendering contest history, rating trends, and problem tag distribution with interactive Recharts components — submission heatmaps, rating history graphs, and tag distribution charts for granular performance analysis
• Engineered a robust data-fetching layer against the Codeforces REST API; implemented sessionStorage caching (capped at 2,000 entries) and graceful retry logic to handle HTTP 429 rate-limiting and minimize network overhead

C++ · SFML · STL (Vector, Queue, Priority Queue)

A real-time graph traversal engine with visual rendering of pathfinding algorithms.

• Engineered runtime execution of Dijkstra & Bidirectional A* optimized for low-latency visual output
• Flattened 2D grid allocations into contiguous 1D arrays — reduced heap fragmentation and maximized L1/L2 CPU cache locality
• Implemented Bidirectional A* with Manhattan distance heuristics, cutting the search space from O(b^d) → O(b^(d/2))
